I have used canna and house and garden,and have to say HnG owns, canna even tell people to use the HnG root accelerator themselves,I personally use the bio 1 part component and their multizyme and root exc,plus top booster and bud xl,along side super thrive, I also have mates that use the Hydro stuff from HnG so that is hydro A,and B,and then the same other stuff as me, and even when he forgets to flush it,it still tastes fine,where as I have mates that use advanced on the same clones and it tastes foul even after a 3 week flush,.
Really can't knock HnG specially when instead of using 2-2.5 ml of every thing you are only using 1ml per litre as its super concentrated,also I trust some one that runs a nursery and had a need for top products,more than I trust a "nutrient company" that cares only for profits,
Heres my latest lady,she gets fed once a week,and maybe watered with ph corrected water with root accelerator and multizyme once a week too if needed.
